Resurrecting this old thread for a little update. A few months ago I sold the 200DX I reviewed above as I was not using it and it had been sitting idle for almost 8 months. Last week had to order a new 200DX and I ended up getting the Tigrunner which I set up on Friday. I had enough time to get it all in order and run a few test beads but I wanted to pass along something that Miller has finally done that is really the icing on the cake for this unit.

On all previous versions of the 200's, changing the tig start parameters used to be a real PIA. First the machine had to be off so if you were welding and wanted/needed to change settings, you had to turn it off. Then, you had to turn it on while depressing a couple of the buttons on front of the unit and then the software would drop you into the hidden menus. Then, you make whatever changes you needed and once again, turn the unit off in order to save the settings. Now, turn the machine back on and you're good to go.

I talked with Miller engineers on several occasions about this and always got the same old line of "the software isn't capable of that". Funny how you don't have to go through all that crap on my 350. Although, IIRC, I used to have to do it on my 300. At any rate, it was a real pain and completely unnecessary IMHO.

So, when I went to check the defaults for the new 200, I read in the manual where you are now able to access the hidden parameter menus WITHOUT going through all those gymnastics. It didn't really offer the info up per-say, rather it just instructs you on how to do the procedure. Suffice to say that it is now MUCH easier to change settings on the new 200's. There will be more to follow in a review I do on the TigRunner package next week.

Well that is refreshing....how about switching modes like from advanced to soft square?
I feel the on-off routine is a bit annoying myself. It wouldn't be quite so bad if the switch wasn't in back.

So far as I could tell, you can change ALL of the start parameters now just by pushing the Amp/Adjust buttons WHILE the machine is ON. I scrolled through everything and the waveforms were right there for the changing. Just reverse the button procedure (hold Amp down first then push Adjust) to go back to welding. Annoying is an understatement, they shoulda done this long ago.

It's been a few days since this thread was active and since then I have purchased a newer 200 DX as well.
The plan is to use both for a while when I am very busy and then when it slows down, sell the older, but still Blue Lightning version and keep the newest version.
In addition to what KB has already so well informed us with I really don't have much to add here.
Other than I purchased mine at my LWS for a bit under $2900. It came by UPS to the store....I cannot believe Miller still uses those cavemen. The box was a bit bent up but the machine was mint.
About the only thing I see different besides access to all functions without turning the machine on and off is, the encoder knob now has a "notchy" feel to it as opposed to the "no friction" feel of the previos models.

200dx

I hate when things like this happen.. I waited to buy this machine while the bugs were worked out of it and then this.. I'm just that **** type of person and things like this bother me. I understand things change and technology progresses but thats when new machines are made...

Join the club

Just use it for a year and then sell it. Then get one with 3 more years of warranty and you are up to date.
Seriously, would you want a Dynasty with less than you have now? This machine has progressed a bunch and will hopefully continue.
I am expecting, now that I have bought my third, Miller to introduce a 250 amp machine on this platform someday....and when they do I will probably be working a way to get one ASAP
Seriously tho, I don't think this hidden menu access is worth upgrading over. It is simply a nice thing that they figured how to do. It doesn't change the machine's capability one bit.
